XP mobile on board with no multiplier adj

[DaffyDrunk]

Thanx in advance for answering my newb question. Looked around and haven't seen ay info that fully answers this question.....

I have a Leadtek WinFast K7nCR18D Mainboard. Early Nforce2 board. It has no multiplier adjustment in the bios. I have an opportunity to sell my 2500+ and thought I'd try a 2400+ mobile. What would this CPU do in this mainboard? I guess I'm wondering how it deals with a bios with no multiplier adjust. If it won't work, is there anywhere that explains how to hard set the XP chip itself to certain multipliers so I'm not stuck a 6x? Any other work around? Just tried that crystal cpuid to see how it works, but after follwing the readme info, it won't let me tweak the multiplier even though I'm sure my 2500+ is an unlocked version.

Thanx for any info...

First, make sure you have the lastest Bios update installed. After, it is not real obvious but I think if you go to the Advanced Chipset Features page in your bios, then set the CPU Interface to "Expert". I did not see this in the mobo manuals, but it says it is an option in the actual bios interface. Hopefully that will display the FSB and multiplier settings. Keep us posted!

It worked for me using strands from speaker wire placed in the socket holes.

I do have an nForce2 board with multiplier adjustments, so I'm not in your boat; but to answer the "What would this CPU do in this mainboard?" question, The chip will probably default to a 5.5 multiplier and you will need to change it either through the BIOS or through the pencil trick or the method MDE suggested.

I think you should just buy yourself a good overclocking board. There's a very good chance that an unlocked desktop 2500 will overclock as high as a mobile 2400 will. Then you'll own a much better board, and instead of having to worry with tricking your motherboard, you will be able to just overclock the sh*t out of your chip. You can get an Abit NF7 for less than $75: link, and if even that's too expensive for you, this Shuttle AN35N is supposed to be pretty decent also: link.

over at the amdmb forums the dfi infinity is being raved the best ocing board to have....but dfi has had problems with dead boards which i believe has gotten better. But for less than 100 bucks and from a good retailer like newegg, it shouldnt be a problem. And one more thing....if you do decide to purchase a dfi infinity board they have dfi technical support over in the amdmb forums (a payed dfi support tech) and other dfi ownders which has helped a lot with my ocing experience.

Oh yeah, if he can spend $25-$30 more for a an AF7-S or a DFI Ultra Infinity, he wouldn't regret it. I was just trying to give him the two best cheap options I could think of, that's all.

Thank you very much for the replies. I got the 2400+M chip, and as expected, it's running 6x. Got it running 1200 MHz for now. Not a big deal since I don't have any new games, but I'd exentually like to crank it up to a decent number. If I can get the nuts up, I might try to "hardwire" the socket or solder the cpu but I'm kinda hesitant about wasting a new CPU. I might go for a new mainboard like you guys have said. I can use this Leadtek for my DAW mainboard or something. Gonna check out the boards you guys were talking about.
Not super rich, but I could afford to throw some money at it since I have to buy another mainboard for my recording computer anyway... I guess I'd kinda like a soundstorm board, but it isn't a huge deal.

Anyone know what the deal is about the crystal cpu id? It seems like I could adjust the multiplier with that but it freezes up whenver I try to adjust the multiplier. I even clocked the FSB to 133, but it still freezes up when I try to up the multiplier... Just curious...

I have a 2400+M and have got it to run at 2267 without changing the multiplier. I could probably go higher with something besides DDR2100 ram. So even if you can't change the multiplier you will probably get quite a good o/c out of it till you can get a better board.

either the wire mod or painting the pins , another option if multiplier changers that fit between the socket and cpu.


with multiplier changers though you have to preset the multiplier , once it is set the only way you can change it again is to remove it from the socket


it works well for dual processor motherboards when you want the option of different multipliers

Daffy, the Abit NF7-S is a SoundStorm board, and it's one of one three motherboards that supports raising the multi over 12.5x on the mobile Bartons. The other two don't have Soundstorm audio: the Asus A7N8X-Deluxe (which is too expensive, and doesn't overclock all that well), and the Abit NF7, which is the same board as the NF7-S, but without the Soundstorm audio and SATA.

The Asus does NOT support manually setting multipliers over 12.5.

What about the Soltek SL-FRN2? I'm running one of those with a XP-m 2400+ and I'm pretty sure I can raise the multipier to 18x or something like that.

I prefer to use conductive trace fluid on the pins rather than wire, I hate the idea of random pieces of wire floating about inside the case. Works fine on my dual setup with 2 x 2500+mobile chips running 18x133

 

[DaffyDrunk]

Thanx for the input. Got the nuts up, and went to the local auto parts store to pick up a rear window defogger repair kit for $12. Basically a little bottle of conductive paint and a brush. Shook it up and used the end of a small paper clip to put the stuff between the pins. let it dry for a few minutes and scraped any excess off the bottom of the cpu to make sure there wasn't any unintended shorts. Then I took a hair dryer to it for about 5 minutes. Set the multiplier to 12.5x for now. Installed and booted. Works! Cool. I upped the fsb to 192 and the vcore to 1.7v. It's currently benchmarking at 2400 and seems to run fine. Idle temp is 50C according to the bios. My case sucks for cooling though. The case is a Packard Bell I modified to fit ATX parts. Thought it would be kinda funny to say I had the Fastest Packard Bell in the world, but the thing obviously just wasn't designed with efficient cooling in mind...

Glad to hear you got it up and overclocking.

Yeah, your next upgrade probably needs to be a new case. Those old cases suck for airflow because the old processors they contained didn't put out near the amount of heat the new procs do.

myocardia, you are dead wrong about the A7N8X-Dlx being able to go higher than a 12.5 multi with an XP-M. I have a rev. 1.04 A7N8X-Dlx and I had to mod the L3 bridges on my 2400m to a high bit sense for me to be able to run a multi higher than 12.5.

Heh, I don't like that idea either, but so far (knock on wood) I haven't had a problem. Not that I haven't had wires fall out, but I haven't had "missing" wires short out anything in two systems that I know I lost wires in.

Either way works. I prefer the wires because I can easily change stuff.

 

[howdyduty]

Nice work Daffy. Thanks for the full story on the results. Great thread.

 

[DaffyDrunk]

So far so good. I'm trying to keep the voltage down to 1.7v to have a more realistic overclock. So far, the 2400+m is still at 2400MHz. Good enough for me and I want to be able to easily/cheaply duplicate a similar setup for other machines. I've only had one hang up in several days of constant use. Need for Speed HP2 froze up on a menu once. Thought it might be from leaving this other game I have running all the time and alt tabbing in and out of it. Once I get a better case and put my custom 80 mm heatsink on it, I think it will be totally reliable setup for super cheap. Amazing CPU for less than $80....
